It solved the problem that the common P3.91 and P4.81 outdoor LED displays brightness is too low before(typical is 4200nits). and the problem that outdoor P3.91 and P4.81 can not do front service.

This design uses smaller scan number which can make the brightness over 6500nits. and the module is dual maintenance design which can be detached either from the front or the back side by a hex wrench. this makes the outdoor front service displays down to 3-4mm pixel pitch level.

It can be widely used for small to middle size displays which needs front service such as displays fixed on the wall, double faces led signs, LED posters, .etc. 

also it is an upgrade solution for outdoor event rentals with our new 500*500mm outdoor dual maintenance die casting cabinet. 

This design makes the popular model of P3.91 and P4.81 now becomes real outdoor and the maintenance much easier.
